12 Claims.

This invention relates to improvements in shaving or hair clippingapparatus.

The main objects of'this invention are:

First, to provide an improved hair clippinglor shaving device of theelectrically actuated mechanical type, wherein the cleaning thereof isfacilitated.

Second, to provide a device of the type described having improvedprovisions for facilitating and expediting the removal of clippings fromthe interior thereof when desired.

Third, to provide a device of the type dc-- scribed wherein theoperation is improved, being substantially less noisyby reason of theelimination of vibration and chattering. I

Objects relating to details and economies of the invention will appearfrom the description to follow. The invention is defined in the claims.The present invention relates to improvements in electrically actuatedmechanical shaving devices of the type illustrated in my Patents No.2,228,768 of January 14, 1941, No. 2,251,455 of Aug #5, 1941, andNo.2,203,021 of June 4, 1930.

ance with the embodiment of Fig. 6 having simi-.

larly pivoted guard elements at each end of the cutter head, the guardelements being shown in operative closing relation to the ends of thecutter head.

Fig. 9 is a fragmentary view illustrating the apparatus of Fig; 8' withthe guard elements thereof in retracted, inoperative position.

Fig. 10 is a modification of the structure illustrated in Fig. 6 inwhich-one of the guard elements is fixedly attached to the cutter head.

In the drawings, the reference numeral I indicates an electricallyactuated mechanical shaving device, which has a handle or body 2 of asuitable size for gripping and adapted to house a motor (not shown). Atits outer end, this handle is'provided with a channel-like recess, asillustrated in the .above identified patents, for receiving an openended cutter head 3, which head is detachably secured to the handle in amanner to be described. The cutter head is provided with a channel-likecutting member i receiving and housing the reciprocable cutter 5 and thehead is provided with spaced openings 6 alined with further openings 1in the handle for receiving the thrust pins 8- for urging cutter 5against the cutter member 4. The head and handle are provided with stillfurther alined openings BI. 82, respectively, to receive the actuatingrod 83 by which cutter 5 is reciprocated F from a motor (not shown).

The invention includes means for accomplishing this reciprocationwithout vibration whereby the device is substantially noiseless inoperation. For this last named purpose, thehead' 5 is provided with arectangular socket or seat 9 and the actuating rod 83 is provided withan enlarged spherical end Ill receiving a cap-like rubber'cushion Hwhich fits within socket 9 .(though with suflicientclearance to allowits removal therefromland serves to reciprocatehead 5 withoutdestructive in side elevation vibration'or noise. The opening 8| in thehead is of sufficient size to enable the head to be lifted up over thecushioned end ID of the rod when it is desired to remove the head fromthe handle.

The outer cutter 4 has rounded sides l3 merging into the fiat face |4thereof, which latter is provided with transverse slots I5 in a wellknown manner forming guard and cutter bars which coact with similarcutter bars on the cutter 5 to furnish a sliding shearing action in awell known manner.

The construction also includes end members or guards I6. I1, the formerof which is fixedly secured to the head 3 by means of a screw l8, whilethe latter is attached to the handle 2 in a manner to be hereinafterdescribed in detail. These guards are provided with rounded portions l9which merge into the rounded sides l3 of the head andalso into the fiatface l4 of the latter, with the result that a cutter having well roundedsmooth sides and ends is provided free from any digging or abrasiveaction in use.

The cutter head is removably attached to the handle by means of atransversely extending tapered parallel sided pin 20 which is similar tothat illustrated in my copending application for patent, Serial No.314,287, filed January 17, 1940, and coacts with the head and handle inthe manner illustrated in that application. Therefore, I deem itunnecessary to particularly point out details of construction andoperation thereof in this application.

The guard ll of the present device is one which is capable of a s ingingaction transverse to the line of reciproc ion of the cutter 5, havingprovision for pivo ally removing and replacing the same from and tooperative position. To this end, the guard I1 is provided with anelongated spring 2| riveted thereto and apertured medially at 22 toreceive a drive screw or rivet 23 which engages the handle and serves asa pivot for the member I! thereon. The spring 2| is preferably placedunder slight flexing tension so as to resist accidental displacement inan angular direction and the extremity or tail 24 thereof is providedwith a projection or lug 25 which engages a suitable depression in thehandle to further resist displacement. In order to insure accuratealinement of the guard with the sides and top of cutter head 4, thelatter is provided with a keeper recess 25 closely engageable by adetent tongue 26| integral with guard H.

In the event that it is desired to remove clippings from the interior ofcutter 5 and the cutter head, the guard member-H may be readily swungmanually to an inoperative position first releas- In Fig. 4, Iillustrate a modified embodiment of the foregoing construction, whereinthe guard element 262 is pivoted directly on the handle by means of adrive screw 2'63 and has an integral fold 264 intermediate its lengthengageable with a keeper recess 265 in the cutter head to'insurealinement of the guard with the shear face of the head. The guard ismaintained in snug end engagement with the head by means of a curvedspring element 256 having one end thereof secured to the handleinteriorly thereof as at 261 and passing to the outer side of the devicethrough an aperture 268 in the handle. A bent portion 269 onthe otherextremity of the spring engages the guard 262 to resiliently thrust thesame against the cutter head end. This provides a structure which iseffective in operation and neat in appearance.

As a modification of the form illustrated in Fig. 4, a spring 210secured by drive screws or rivets 2'|| directly to the outer surface ofthe handle may be employed, this spring having engagement with the guard262 in a similar manner to that discussed in connection with Fig. 4. Ineither of these embodiments, the guard 262 is shiftable to expose theend of the head in the same manner as in the structure of Figs, 1 to 3The detent portion of the guard is merely removed from its keeper recess2B5 byfiexing the thrust spring associated therewith, whereupon theguard may be swung in a plane at right. angles to the head.

, In Figs. 6 to 10, I illustrate a modified embodiment of .my invention,including a hingedly mounted guard element 21 adapted to swing in theplane of reciprocation of the cutter, being pivoted on a pin 28 in arecess in the handle, which pin is arranged transversely of that plane.This guard element has an extension or leg 29 offset therefrom slightlyless than 90", which extends into the channel-like recess 30 of thehandle 3| wherein the cutter head 32 is received and is engaged by thelatter in operative position as illustrated. Being at less than a rightangle to the guard, the extension or leg 29 is flexed somewhat tomaintain the guard snugly against the endof the head. This extension 29is provided with'a suitable aperture or recess 33 for receiving thethrust pin 8 and permitting limited outward movement of the guard, asillustrated in Fig. '7.

In utilizing the device of Figs. 6 to 10, when it is desired to cleanthe cutter, the tapered retaining pin 20 is withdrawn, whereupon theexing the detent tongue 26L and the clippings removed without removingthe head from the bandle. The guard Il'is then swung back to operativeposition and held there by spring tension as described. However, in theevent that it is desired to remove the hea'd'a'nd cutter from the handlefor more thorough cleaning or sterilization, the securing pin 20 may beremoved as described in my application, Serial No 314,287, identifiedabove, and the head 4 separated from the handle, carrying with it theguard l6. Once the cushioned actuating member 83 is freed from thecutter 5, the'latter may be readily slid outwardly from the recess inthe head in which it is received. V

All of the foregoing details contribute to a razor structure which issimplified in nature and much more easily manipulated for cleaning andthe like than presently known devices.

tension of the guard element which is under flexing tension, as pointedout above, urges the head upwardly while at the same time the guards 2'!swing outwardly and the cutter 5 may be freely removed from the handle.Upon replacement of the cutter to operative position relative to thehandle, the guard is automatically swung to operative end engagingrelation to the cutter head, there being no need for detents or otheralining'devices.

Reinsertion of the pin 20 locks the parts in operative relation.

It will be understood that the swingable guard elements, such as I haveillustrated in Figs. 4 and 5 and Figs. 6 and '7, are adapted to beassociated with a cutter head having an opposite guard l6 securedthereto in the manner illustrated in Fig. 2. I have illustrated such adevice having a guard fixedly mounted on the cutter head in Fig. 10.However, it will likewise be apparent to those skilled in the art thatin-eachof these embodiments it is very possible and highly practical toduplicate the swingable guard structure at each end of the cutter head.I

have illustrated this type of structure in Figs. 8 and 9, usingreference numerals similar to those appearing in Figs. 6 and '7. In theevent hinged elements are utilized at each end of-the cutter head inaccordance with the disclosures of Figs, 6-10, it is evident that itwould no longer 'be desirable to urge the-cutter head laterally relativeto the handle by inclination of the tapered pin. Hence, in these figuresI have illustrated that pin as exerting merely a downward force. Snugengagement of the guard elements lieved this disclosure will enablethose skilled in the art to embody or adapt may be desired.
